Speedy Sabotage (Su)

Vexgits are adept at disassembling machinery, reducing even complex devices to trash with shocking speed. When using the Disable Device
skill, these gremlins treat all devices as being one category simpler
for the purposes of determining how long it takes to use the skill.
Thus, difficult devices count as tricky, tricky devices count as simple,
and simple devices can be dismantled as a free action.

Wrecking Crew (Su)

A group of up to six vexgits can work together to dismantle a device. This ability functions like the aid another action, but a single vexgit can receive help from up to five other vexgits, granting it up to a +10 bonus on its Disable Device check.

Maniacally destructive little brutes,
vexgits delight in scrapping and sabotaging the works of larger races.
The larger and more complicated the target, the better. While one of
these spiteful gremlins might delight in trapping someone behind a door
with a jammed lock, loosening the wheels on a carriage, or sneakily
removing all the nails from a small boat, it’s when groups of vexgits
get together that they’re truly dangerous. In such instances, the
portcullis of a vexgit-infested gatehouse turns into a deadly weapon,
while a clock tower becomes an avalanche of gears waiting to topple.
Engineers warn apprentices of masterful Constructions destroyed by these
unruly gremlins, with many blaming their greatest failures on such tiny
saboteurs.

Like most gremlins, vexgits prefer to live
underground, but cities and the devices they find there fascinate them,
often drawing mobs of the dangerous fey to sewer tunnels and abandoned warehouses.
